جب جسم آرام سے ہوتا ہے یا یکساں کونیی رفتار کے ساتھ گھومتا ہے تو اس میں _____ ہوتا ہے؟
Answer: All of these
Explanation Zero torque → No net torque is needed to maintain constant angular velocity or stay at rest. Zero angular acceleration → Uniform angular velocity means no change in angular speed. Rotational equilibrium → Occurs when net torque is zero, so the body is either at rest or rotating uniformly.

Answer: 52g
Explanation To get max Cr from Cr₂O₃, use the mass fraction of Cr in Cr₂O₃. Molar mass Cr₂O₃ = 2(52) + 3(16) = 104 + 48 = 152 g/mol Mass of Cr in 1 mol = 2(52) = 104 g So Cr mass = 76g × (104/152) = 76 × 0.684 = 52g Last verified on 11-04-2026
